Pylint 在输出中显示无效的变量名称 [英] Pylint showing invalid variable name in output

问题描述

我制作了一个简单的 Python 脚本来在网站上发布数据.

I made a simple python script to post data on a website.

#Imports

url_to_short = sys.argv[1]

post_url = 'https://www.googleapis.com/urlshortener/v1/url'
headers = {'Content-Type': 'application/json'}

data = {'longUrl': url_to_short}
post_data = json.dumps(data)

req = urllib2.Request(post_url, post_data, headers)
resp = urllib2.urlopen(req)

if resp.getcode() == 200:  
    content = json.loads(resp.read())

#Other stuff

现在我想让我们用 pylint 工具检查我的脚本的编码标准.

Now I thought lets check my script for coding standards with pylint tool.

我的pylint输出如下:

************* Module post
C:  1,0: Missing docstring
C:  6,0: Invalid name "url_to_short" (should match (([A-Z_][A-Z0-9_]*)|(__.*__))$)
C:  8,0: Invalid name "post_url" (should match (([A-Z_][A-Z0-9_]*)|(__.*__))$)
C:  9,0: Invalid name "headers" (should match (([A-Z_][A-Z0-9_]*)|(__.*__))$)

# Other stuff

现在，我的问题是为什么 pylint 将我的变量名称显示为 Invalid name.以这种方式命名变量是否是错误的编码约定.

Now, my question is why pylint is showing my variable names as Invalid name. Is naming variable this way a wrong coding convention.

我的完整的pylint输出.

推荐答案

由于您的代码未包含在类或函数中，因此期望这些变量为 常量，因此它们应该是大写的.

As your code is not contained in a class or function it is expecting those variables to be constants and as such they should be uppercase.

您可以阅读PEP8了解更多信息.
